Sinocyclocheilus grahami

The golden-line barbel (Sinocyclocheilus grahami) is a species of cyprinid fish endemic to Dian Lake and its tributaries in Yunnan, China. It has been extirpated from the lake itself due to heavy pollution, but survives in a single tributary and a few small temple ponds. This species can reach a length of 23 centimetres (9.1 in) though most are only around 17 centimetres (6.7 in). The greatest weight known for this species is 250 grams (8.8 oz).
